Update: Who is still in first stage of labor. Starting to do more nesting, stopped eating at noon today and should have them some time tonight or tomorrow morning. I have to take her out on leash to potty, off leash even in my fenced yard she is trying to find a place to hide. The yard is large enough and with lots of trees, holes and brush to lose her........

Update: Who has been restless, nesting and very uncomfortable on and off. She has also refused all food except for some Nutri-Cal. Luckily my vet is open on Sunday mornings, I called and we decided to be safe and take her in to check fetal heartbeats. This is done to ensure that the pups are not in distress, if they are then we do a c-section. Results are that the pups are not in distress, Who is also not is trouble at this stage, just going to take a bit longer. Vet says to give her another 24 hrs, if nothing is happening, we go back and check again.
This pic was taken last night about midnight, she had been nesting a bunch then tossed herself down onto her back for a long nap.
